Heyas Toleda. I finally got around to installing the ALC898 kext from Multibeast for my new mainboard (only took me 2 months). Everything works as it should (optical as well), except of course the green jacks. Perhaps the no audio on the Z77X-UD5H is due to the TI DRV632 line drivers used as the headphone amps for the green jacks?

Good to hear you audio is working. Your theory may be correct, not considered previously. Gigabyte has acknowledged a circuit problem (not enough power to start the green and grey amps) on v_1.0.; more info, GA-Z77X-UD5H audio green-port problem solved by welding 2 resistances.

So i've managed to get 10.8.3 fully running on my Zotac ID-11 and following your guides i'm getting onboard audio with the legacy ALC888 from multi beast. However i'm having difficulty getting my HDMI audio to show up, can someone please assist me with this i have attached my DSDT file. I've had about 3 hours of sleep in the last 48 hours trying to get this to work

i'm having difficulty getting my HDMI audio to show up

Ion HDMI audio does not work in OS X.

Really why is that so, it works perfectly in Ubuntu you would think it should be pretty easy to setup. If i install VoodooHDA 2.7.3 it shows up but i get a crackling noise if i play any sound.

The installed AppleHDA.kext is not from MultiBeast, can't help. The IOReg shows the phantom codec problem indicating no onboard audio in OS X.

Hi toleda
I have x58 ud7 and gtx480 I install applehda alc 889 from MB.I need to get HDMI audio via gtx 480.Can you look my dsdt and ioreg thank you.
I try your idia like this
You didn't look in the right place, with the above layout-id is Audio ID is 889. As Post #1 of this thread notes, Audio IDs for Mountain Lion have changed. For ML, the Audio ID is now 1. Run MultiBeast 5.2.1 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/With DSDT/ALC889.

MultiBeast will install the ML AppleHDA.kext and edit dsdt/HDEF/layout-id to 0x01, 0x00, 0x00, 0x00.
